It may be a longshot, but I'm hoping I can find a (67/68 vintage stepside) tailgate that may have damage rust, yet the center section with the stamped "CHEVROLET" intact.
On my Utility bed truck, I have a "READING" Utility gate, ...that I am hoping I can modify by welding in the stampted "CHEVROLET".

I hate to cut up a good used/repro tailgate to do this, but it may come to that.
